Have you ever had this said to you? I have, lot’s of times, when I was still struggling with my religious beliefs, or lack thereof. It was usually in the context of a conversation about comparative religions, and which religion was the correct one. Someone would point out that those Muslims, or those Hindus or those Jews worshiped a different god than I did, to which someone else would say (indeed, many times I would say it) “It doesn’t matter. There’s only one God. It’s all the Same God”. That was supposed to smooth things over, make us all nicey-nice.
The point of this little tidbit of rationalization is an acknowledgment that there are different gods, worshiped by different cultures in different parts of the world, but in the end, while they may all give Him a different name, he’s still the same guy. He’s God (Yahweh, Allah, Vishnu, etc). It’s not so much that there are competing gods, just competing cultures vying for the naming rights.
But you know, they’re right, come to think about it. There really is one god. It doesn’t matter which culture it arises from, be it an ancient, pagan religion that we have no record of, localized among a tribe of Neanderthals 50,000 years ago, or the Christian god of the Catholic Church, and its many protestant offshoots. It’s still the same, one true god. That god was created in the minds of man. It was created as a response to questions and mysteries of the times, to reassure men that they were not alone in the world, that there was a higher being out there somewhere who kept a watchful eye on them, and who protected them in bad times and nurtured the good times, as long as they performed the right rituals and said the right prayers. That same god was created by different men in different cultures at different times, for the same reasons.
So in that respect, it is all the same god.
